SNAP-snai..

Specification of Letters Patent.

Patented' May 25, 1909;

Application filed. March l1, 1909. Serial No. 482,779.

To all whom it may `concern:f

Be it ,known that I, EDWARD J. BROOKS, a citizenof the United States of America, and a resident of. East Orange, in the State of New Jersey, have invented a new and useful Improvement in Snap-Seals, of which the Thls invention relates, in common with' ypreviousy improvements, to self-fastening seals or F snap seals yas they are commonlyv termed, for use kas substitutes' for lead and wlre seals and other press fastenable sealing devices to secure the doors of railway freight cars' andfo'r other like purposes. Examples of such snap seals are set forth in my specificatlon yformlng part of United- States Letters Patent', No. 'eizsiydated February. 16,

' 1909 and in my previous specification therein referred to. y

n The presentinvention is more particularly `additional to the improvement in snap seals set rforth in my specification forming part of said Letters Patent No.f912534.

.The leadingobject of the present" inven-L tion is to rovide in la .two-part snap seal, made ywhoi y of sheet metal, for interlocking Lthe shackle ends with each other within the seal part, as additional means for rendering the seal secure against being violated with out detection. f f

rOther Objects will be set forth in the gen#k eral description which follows.

The invention consists in certain novel combinations of peculiarly constructedparts, and inl'an improvedsnap seal embodying such combinations Lor either 'of them, as hereinafter more particularly described and claimed.`

v A sheet Of drawings accompanies this specification as art thereof.

Figures 1 an 2 are respectivelyface edge views of the shackle ofthe improved seal shown fiat excepting its permanent i bendsgjFigs. Band ly are respectively a top view and a longitudinal section .through the partly formed seal part; Figs. 5 and 6 are `sectional edge` viewsyshowing respectively the seal part and shackle as prehminarily unlted, and as they'appear after the sealv is @snap fastened; and yFlg. 7 is a fragmentary wperspective view of the interlocked-shac'kle ends;

Like ference characters refer to like parts in all the ligures.

The improved seal is composed of a flexicomplete from 'a single piece of suitable sheet metal, that of the shackle being preferably the harder so as to be resilient, but by proper selection both parts may be made of one and the same metal.

Of the respective shackle ends, 1 and 2. the former is constructed with a transverse corrugation, 3, and with a suitably bent catch portion, 4, of reduced width extending beyond said corrugat-ion. The other shackle end, 2, is constructed with a catch hole, 5, near its extremity and with a pair of spurs,

6 and 7, formed by making V-sha ed incisions in the sheet metal and ben ing the partly severed points Outward on opposite sides. The face or both sides of the shackle may be provided with the customary per- `marient distinguishing marks, as illustrated by BJERRAYSQ in Fig. 1.

Thevseal part l) is preferably and Couveniently oval in shape, and includes a central' label portion, 8, having embossed or printed distinguishing marks represented by BJERR v.N ew York in Fig. 3, surrounded by a tubular portion, 9, shown in its completed form in Figs. 5 and 6, withv its seam, 10,

adjoinin'gthe edge of said label portion, and with its inlet hole, 11, and a pair of rigid in- 1 wardly projecting lips, 12 and 13, at the sides of saidainlet hole, located at the front or back ofjtheseal part as may be preferred. Said corrugation 3 of the shackle a interlocksk with the inturned edge or seam 10 `of the seal part l), at the larger end of the tubular rim 9, andjits catch 4 extends beyond said corrugation within saidk tubular. rim as shown in Figs. 5 and fi.k The two parts of the seal are thus preliminrily united at the factory. y

To'obviate otherwise fastening/the shackle end 1 to keep the catch 4 in effective position vfor the snap fastening operation, the shackle a is preferably given a substantially circular form as in Fig. 5 sothat the strain thereon in the press fastening operation will not tend to move the catch 4 away from the inlet 11.

' In the `press fastening or sealing operation the extremity of .the shack-le end 2, after entering the inlet 11,* interlocks with the catch 4; the shackle end 2 and catch i'mutually yielding or iiexing to a sufficient extent, and resuming their original forms by the resili'- ency of the metal, so that the catch4 pro-- jects through the catch .hole 5 in the fastened ,seal as represented in Figs. 6 and 7. ble shackle, a, and a seal'part, b, each formed.'

Simultaneously, the spurs and 7 pass the 'Y' lipsfl and 13 apart after-e tional security spnrs'- as the' primary locking of the shackle ends With each other I b v means ol said catchilV and catch hole 5 1 aford .such additional securityf as herein- The'A shape of vthe seal before stated. -f part b may obvicusl)7 `,be. changed at Will without affecting. the

- operation of. the seal; andv other like inodii- `cations will suggest themselves to those skilled in the art. I y

Having thus described said improvement, I claim as my invention and desire to patent under this speciie-ation:

1. The combination., in a snap seal, of a sheet inetal sealpart constructed with a central label portion and with a tubular riin having its seam adjoininhj` tionpermanentlv fastened in said seam and fastening,- lthe intersaid label4 portion 'z andy provided with an -inlet hole, and al resilient shackle of sheet metal having one end constructed with atransverse eorruga- 1 a suitabl)T bent snap catch extending beyond ithe saine'within said rini and with a catch 'lhole adapted to interlock with said catch al gits other end. Y

Th combination, in a snap seal, ol a sheet-metalseal part constructed with a l central label portion and Witha tubular rim having,rv its seam adjoining said label portion 1 and provided Withan inlet hole and inwardly `projee Ling lips -at the sides of said hole, and i a resilient shackle of sheet metal having' one .l end constructed with a transverse corruga- 'g tion permanently fastened in said seam and l a suitably bent snap catch extending beyond g the rsaine' Within said rim and With a catch hole adapted to interlock with said catch at its other end and oppositel7 projecting spurs 'l adjacent to said catch hole ada ted to interlock with said lips, substantia l Y as hereinl before specified.
